On 31 August 2018, ATCO Gas Australia Pty Ltd submitted a proposed revised access arrangement for the Mid-West to South-West Gas Distribution Systems (GDS). The Access Arrangement period is due to commence 1 January 2020 and finish 31 December 2024. This will be the fifth access arrangement period (AA5).
The GDS consists of gas networks servicing Geraldton, Bunbury, Busselton, Harvey, Pinjarra, Brunswick Junction, Capel and the Perth greater metropolitan area (including Mandurah). These combined networks supply approximately 750,000 customers through more than 14,000 kilometres of gas distribution pipelines.
On 11 October 2018, the ERA published an issues paper to assist interested parties in preparing submissions on the proposed revised access arrangement. The issues paper was not intended to be an exhaustive review of the proposed revised access arrangement or the matters that the ERA will address when making its draft decision on whether to approve or not approve the proposal. The ERA received six submissions by the deadline of 14 November 2018, and accepted a late submission from AGL Energy Limited.
On 18 April 2019, the ERA published its Draft Decision on the proposed revised access arrangement for the Mid-West and South-West Gas Distribution Systems. In response to the Draft Decision, ATCO submitted revisions to its proposal on 12 June 2019.
Interested parties were invited to make public submissions on the ERA’s Draft Decision and ATCO’s revised proposal. The ERA received eight submissions by the deadline of Wednesday, 10 July 2019.
